Recruiting

• Conditions: Postoperative Pain

• Registration Number: NCT05681091
• Lead Sponsor: The Second Affiliated Hospital of Chongqing Medical University

Brief Summary

This study aims to observe the impact of perioperative body temperature on postoperative pain and pain sensitization for the patients with laparoscopic surgery. Based on this study the investigators aimed to explore the effect of perioperative hypothermia on postoperative pain.

Detailed Description

This study aims to included surgery patients to observe the impact of perioperative body temperature on postoperative pain and pain sensitization for the patients with laparoscopic surgery. Body temperature and postoperative pain will be continuously assessed, and then association analysis will be performed.

Primary Outcome Measures

Name	Time	Method
Patients' pain score after surgery	From ending of the surgery to 24 hours after anesthetic resuscitation	The patients' pain score was tested with Numerical analogue scale of pain (0-10, 0 represents pain free, and 10 represents unbearable pain).

Secondary Outcome Measures

Name	Time	Method
Patients' pain score during postanesthesia care unit	From ending of the surgery to the time when discharge from postanesthesia care unit with a mean of 30 minutes after surgery	The patients' pain score was tested with Numerical analogue scale of pain (0-10, 0 represents pain free, and 10 represents unbearable pain).
Pressure pain threshold	From beginning of the surgery to the time when discharge from postanesthesia care unit with a mean of 30 minutes after surgery	the patients' pain threshold was tested by tenderness meter.
